Background: Shoulder-hand syndrome (SHS) is one
of the common sequelae after stroke, which not only hinders the recovery
of patients, but also increases the economic burden of the family. In
the absence of effective treatment measures, acupuncture treatment has
been widely used in China to treat post-stroke shoulder-hand syndrome,
but the details are unclear. Therefore, this review aims to evaluate the
true efficacy of acupuncture in patients with SHS.
Methods: We searched eight databases [PubMed,
Embase, Web of Science, Cochrane library, China Biomedical Literature
Database (CBM), China Science and Technology Journal (VIP) database, the
China National Knowledge Infrastructure (CNKI) database, and Wan fang
database] from its inception to March 2025, randomized controlled trials
(RCTs) of SHS acupuncture treatment combined with rehabilitation
(Rehab). Two investigators independently used pre-designed forms to
extract valid data from eligible randomized controlled trials.
Meta-analysis was implemented through the Rev. Man software (version
5.4). The strength of the evidence obtained was implemented using the
GRADE profiler software. Adverse events (AEs) were collected by reading
the full text and used to evaluate the safety of acupuncture treatment.
Results: Forty-seven studies, involving 4,129
participants, met the eligibility criteria, and were included in the
review. Overall meta-analysis showed that combined acupuncture
rehabilitation significantly improved motor function (upper-limb
Fugl-Meyer Assessment (FMA): 41 studies, mean difference (MD) 9.50, 95%
confidence interval (CI) [8.47, 10.53]) and pain reduction (visual
analog score (VAS): 37 studies, MD: −1.49, 95% CI [−1.66, −1.33]). It
also improved activities of daily living (ADL) compared to
rehabilitation alone (ADL: 17 studies, MD: 11.94, 95% CI [8.26, 13.63]).
There was no significant difference in the occurrence of adverse events
(AEs) between acupuncture treatment combined with Rehab and Rehab alone
(p > 0.05). The certainty of the evidence was rated low level
because of flaws in the study design and considerable heterogeneity
among the included studies.
Conclusion: This review found that acupuncture
treatment combined with Rehab treatment may have a positive promoting
effect on improving motor function, reducing pain, and improving daily
living ability in SHS patients. However, due to the existing
methodological quality issues, our findings should be treated with
caution. Future high-quality studies are urgently needed to validate our
findings.

1 Introduction
Stroke is the second largest cause of death worldwide
and the first leading cause of acquired long-term disability, leading to
an annual global economic burden (1).
Post-stroke shoulder hand syndrome (PS-SHS), also known as post-stroke
complex regional pain syndrome, is experienced by more than 50% of
stroke patients (2),
it usually occurs between 2 and 3 months of an acute event and usually
presents with pain, hyperalgesia, joint swelling, and limited range of
motion (3).
Post-stroke shoulder hand syndrome is difficult to treat, and its
symptoms may persist for a long time, resulting in limited upper limb
function or even irreversible permanent apraxia (4, 5).
In addition, SHS may hinder the overall recovery, prolong
hospitalization, limit the patients’ activities of daily living (ADL),
reduce the quality of life, and bring heavy economic burden on the
patients and their families (6).
Currently, commonly used treatments for post-stroke SHS include drug
therapy, soaking in cold water, physical therapy (PT), occupational
therapy (OT), psychotherapy, and sympathetic block (7, 8).
Although these conventional treatments were initially found to be
effective, their adverse effects cannot be ignored. Low-dose oral
steroids are effective in improving the SHS after stroke (9),
for example, to avoid adverse effects associated with long-term drug
use, steroids are only indicated for short-term treatment and are
considered a difficult factor for long-term post-stroke SHS (5), early referral to PT, OT, and psychotherapy may prevent the progression of symptoms (10).
However, the disadvantages of these approaches, such as high healthcare
costs, increased workforce investment, and increased demands for
patient collaboration, have also received attention. In addition, the
expertise of rehabilitation therapists varies from different regions,
which will affect the treatment effect. The incidence of SHS after
stroke remains high and is a challenging problem to be addressed. To
date, consistently effective and good patient compliance methods are
still lacking (11).
As a basic therapy for the prevention and treatment of
traditional Chinese medicine (TCM), acupuncture has been used in
clinical practice in China for thousands of years (12).
According to the site of application, acupuncture can be divided into
abdominal acupuncture (AA) and scalp acupuncture (SA). In addition,
according to the surgical method, acupuncture can be divided into manual
needle (MA), electro-acupuncture (EA), and warm acupuncture (WA) has
been proved to have the advantages of low price, good effect and simple
operation (13).
Moreover, as a non-pharmacological intervention, acupuncture has better
efficacy on chronic diseases difficult to treat with traditional
treatment methods, such as low back pain and renal disease (14, 15).
As a result of these advantages, acupuncture has received continued
interest from the general public and health professionals (16).
Furthermore, more medical institutions are using acupuncture clinically
and show that acupuncture can be used as a prospective therapeutic
measure to improve motor function in patients with SHS (6, 17).
In the last few years, three reviews have been published on acupuncture for SHS. The meta-analysis published in 2018 (18)
only evaluated the effect of manual acupuncture on the treatment
efficacy in patients with SHS, and manual acupuncture represented only
one acupuncture form, and the findings were necessarily limited. The
meta-analysis published in 2019 (19)
included only 13 studies totaling 1,040 patients, an insufficient
sample size, and only evaluated the effect of electroacupuncture effects
in SHS patients, and the findings were limited. The meta-analysis,
published in 2019 (20),
selected FMA, VAS and ADL as outcome measures. The results showed that
acupuncture treatment had excellent efficacy in relieving the symptoms
of SHS. However, the intervention did not involve warm acupuncture.
Therefore, we conducted a systematic review of the latest evidence on
acupuncture (including warm acupuncture) as an add-on treatment for the
clinical treatment of post-stroke SHS. Furthermore, with the widespread
use of acupuncture treatment, more research is published in recent years
(17, 21).
Therefore, the aim of this review was to explore the effect of
acupuncture treatment on the relief of clinical symptoms in patients
with SHS and to update previous published reviews.
